4. Operation
4.1 Setup
To achieve optimum compensation in accordance with character of the load controlled, the controller
has a number of parameters that govern its operation. Table 4.1 shows a list of the parameters. The
following chapters describe each parameter, its meaning and how it can be edited.
4.1.1 Editing Parameters and Clearing Recorded Measurement Values
4.1.1.1 Parameter Editing
The controller’s parameters are set to default values, which are shown in Table 4.1, when shipped.
To achieve optimum compensation results, it is sometime necessary to change some of the values in
correspondence with particular requirements; in the other situations it is at least necessary to enter the
measurement voltage type (phase or line) and current transformer turns ratio, within installation of the
instrument.
If parameter edit is enabled (see next chapter), you should proceed as follows:
1. Switch controller to parameter display mode by pressing button P ( for NOVAR-11xx
models only ).
2. Find parameter you want to edit by pressing the ▲, ▼ buttons repeatedly.
3. Press button P ( ►) and hold it down until the display starts flashing.
4. Release button P ( ►) and set the value desired with the ▲, ▼ buttons. Some values
can be incremented or decremented continuously by holding down the ▲or ▼ button.
5. When the value desired is displayed, press button P ( ►). The value will be saved in the
controller’s memory, the display stops flashing and editing is thus complete.
4.1.1.2 Clearing Recorded Measurement Values
Recorded measurement values specified in Chapter 1 can be cleared in an analogous way:
1. Switch the controller to the measurement value display mode ( for NOVAR-11xx models
only ) and scroll to the value you want to clear using the ▲, ▼ and M ( or ▲, ▼ and
► for NOVAR-10xx models ) buttons.
2. Press the M ( ► ) button and hold it pressed until the displayed value starts flashing.
3. Release the M ( ► ) button and by pressing the ▲or ▼ button change display to show
(= clear). The following press of the M ( ► ) button will clear the value.
Clearing a value clears all the other values in its group and starts over their evaluation.
4.1.1.3 Enable / Disable Parameter Edit
When shipped, the controller has the Parameter Edit feature enabled, that means the parameters can
be edited freely on power supply voltage connection as desired. After being put in operation,
Parameter Edit can be disabled to protect the controller against unauthorized changes to its mode of
operation.
To see if Parameter Edit is disabled or enabled, check parameter 00. It can contain the following:
